In Situ Raman and Reflectance Spectra of Iron Electrodes in Borate Buffer Solution Containing 2,2′‐Bipyridine

In situ Raman and reflectance spectra of iron electrodes in borate buffer pH 8.4 containing 2,2'‐bipyridine (bipy) have been investigated. In the potential range where is expected to be formed the in situ Raman and reflectance spectra were identical to the resonance‐enhanced Raman and absorption spectra of the complex, respectively. The results have shown that in the presence of bipy the equilibrium is displaced to the right as a result of the formation of the complex.
